Attrition is an information security-related website, updated at least weekly by an all-volunteer staff. Until 21 May 2001, Attrition maintained the largest mirror of defaced (or cracked) websites available on the World Wide Web. The defacement mirror has since ceased updating. The site contains a variety of information, including movie and music reviews, poetry, and security tips covering topics like forensics, data theft, and security advisories.
Republican communications aide Todd Shriber was sacked from his job after he attempted to hire Attrition to crack his former university website.
In 2001, attrition.org was given a cease and desist order by lawyers of MasterCard for posting parodies of its "Priceless" advertising campaign, which violated copyright law.
Attrition formerly hosted several electronic mailing lists relating to information security, such as InfoSec News. It also maintained the Data Loss Database, which records the data breaches at companies.
